I have a lot of custom type items in my new WP project, and for navigation reasons, I want to make the parent to some of them a Wordpress page. The problem is that apparently, Wordpress does not let you establish parent-child relationships between items with different post type.

Thank you for such a well thought reply. I tried number 1 by setting post_parent to my desired parent id via the database, but it doesnt work, wordpress starts doing weird stuff with that post, and it does not display at all when you open it. Any ideas? The rest of the solutions would not work for our case, because the navigation relies on the parent-child relationships, not on custom taxonomies or meta fields...
